Abstract
The title compound (IV), which is the first example of a well characterized solid containing the TeH- anion, can be prepared by treatment of the ethylenediamine extracts of the alloys K2SiTe3 or K2GeTe3 with (PPh4)Br.
ChemInform Abstract
The title compound (IV), which is the first example of a well characterized solid containing the TeH- anion, can be prepared by treatment of the ethylenediamine extracts of the alloys K2SiTe3 or K2GeTe3 with (PPh4)Br. (IV) is isomorphous with tetragonal (PPh4)Br (I4, Z=2). The structure consists of isolated TeH- and PPh4+ ions. The crystals slowly decompose at 25 °C while solutions of TeH- have only limited stability at 25 °C.
